This means that 92% of the total codeine/caffeine was extracted into a net volume of 750ml. (1.47g codeine, 2.74g caffeine) What remains in the beaker is mostly junk & aspirin. Reduced volume
in 2nd beaker to 150mL by boiling. The room fills with the mild smell of vinegar as some of the aspirin decomposes. The solution is cooled in the fridge and then filtered (1). Then the volume
is again reduced to 50mL. The solution is cooled in the fridge and then filtered (2). After this treatment, less than 15% of the original amount of caffeine will remain in the solution.

What remains is a solution of codeine without a discernable amount of caffeine that leaves a truly euphoric stoning codeine buzz. The solution can be boiled down to a powder that looks something
like brown sugar and is intensely bitter (unlike caffeine, that is only mildly bitter). This is a relatively concentrated form of codeine phosphate that you're after. Rejoice! Responsably enjoy
the fruits of opiate gods.

Some amount of caffeine is filtered off at this step. Remember to wash your filter paper with a bit of ice-cold water to reduce the losses. What you're doing is actually recrystallizing the
caffeine, and for people who haven't seen it before, it almost looks like cotton candy.

More caffeine is filtered off at this step.

If you don't have automated stirring, just stir occassionally over a half-hour period of time.

Note how this technique also does not use any acids, bases or organic solvents to accomplish the removal of caffeine from the caffeine/codeine, and thus I feel is a significant breakthrough.

Chromic would like to congratulate a name-withheld codeine fanatatic who he worked alongside with (well, via private messages) to work out this technique.
